摘要： The present disclosure pertains to a transmitting node (10) for a wireless communication network. The transmitting node (10) is adapted for transmission utilizing independently controllable antenna elements of an antenna arrangement (24). Moreover, the transmitting node (10) is adapted for switching between different beams and/or subsets of the antenna elements for transmission based on transmitted power in relation to EMF exposure limits. There are also disclosed related devices and methods.

摘要： The present invention pertains to the field of wireless transmissions and presents exemplary methods for and designs of wireless communication devices. According to one example embodiment, there is provided of a wireless communication device (1), which comprises one or more proximity sensors (5), an antenna arrangement (3) and processing circuitry (7). The processing circuitry (7) is configured to obtain a sensor output (9) from the one or more proximity sensors. The processing circuitry (7) is further configured to control an operation of the antenna arrangement (3) to spatially steer electromagnetic energy transmitted from the antenna arrangement (3) based on the obtained sensor output (9). In exemplary embodiments, the processing circuitry (7) may be configured to control the operation of the antenna arrangement (3) to spatially steer the electromagnetic energy transmitted from the antenna arrangement (3) away from an obstructing object (2) whose proximity has been detected based the sensor output (9).

摘要： A method and an antenna arrangement are disclosed for reducing the antenna radar cross section for an externally illuminating radar source. A radar pulse is transmitted with the antenna arrangement fully matched to achieve lowest possible power loss of the pulse. At all other times the antenna will be poorly matched and thereby acting as a low radar cross section. The reduced radar cross section leads to an antenna gain reduction, which most often Can be accepted since competing noise is reduced as much as the useful signal. It is further suggested that the range gate of the receiver and the transmitter pulse control the antenna. Thus the antenna is 'fully opened' during the transmitting pulse and may be partly or 'trade-off' matched during range gate reception. In the interval of not transmitting or receiving the antenna will present a low radar cross section.
